Application fil'ed' March 8, 1926. Serial no. 93,258.

The present application is a modification of the embodiment shown in myPatent No. 1,625,306 of April 19, 1927, for improvements in washingattachments for tubs,

The principal object of the present inventionis to provide an airinjector which is adapted to operate in association with any suitablesource of air.

Another very important object of the invention is to provide anattachment of this nature which is exceedingly simple in itsconstruction, in that it is capable of being quickly, expeditiously, andeasily assembled and disassembledand may be manufactured at a very lowcost, and yet will prove thoroughly reliable and efiicient in use.

lVith the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in cer tain novel featuresof construction, and in the combination and arrangement of parts as willbe hereinfter more fully described and claimed.

In the drawing Eigure 1 is a sectional View through a tub showing myimproved attachment in sectional elevation, and

Fig. 2 is a top plan view thereof.

Referring to the drawing in detail, it will be seen that 5 designates atub which may be provided with the cover 6, and in the present instance,one wall of the tub is provided at its upper edge with a notch 7. Thistub has been shown merely by way of example, and may be in the nature ofthe ordinary household tub or of a much larger variety, such as would beused in laundries of the commercial type.

Referring in detail to the attachment, it will be seen that 8 denotes apipe which has a flattened portion 9 for reception in the notch 7 not tointerfere with the closing of the cover 6. This pipe 8 terminates at itsinner end in depending extension 10,,

externally threaded for receiving the internally threaded collar 11 of avertically disposed pipe 12 that depends inwardly into the tub. Thebottom end of the pipe 12 is zilso externally threaded as is indicatedat 13 for receiving a T coupling 14. The pipe 81s adapted to beconnected in any suitable manner as indicated at 15 with a source ofcompressed air.

When the attachment is "to be used with a household tub, an ordinaryvacuum cleaner may be used as a source of air.

However, in a commercial laundry, it would probably be preferable to useair compressors or the like.

A nozzle frame indicated generally by the letter A is attached to thecoupling 14, and extends over the bottom of the tub. This frame may beof any desirable shape and formatiombut in the present instance, I haveshown a form which has proved practical. This form of the frame isrectangular including side perforated pipes 16, end perforated pipe 17and a pair of end perforated pipes 18. The pipes 18 are threadedlyengaged with the T coupling 14. Elbow couplings l9 connect the end pipes18 and the end pipe 17 with the side pipes 16. The plane of the frame Ais disposed at right angles to the pipe 12 and therefore is disposedhorizontally It is thought that the construction, utility, andsimplicity of this invention will now be clearly appreciated by thoseskilled in this art without a more detailed description thereof.The'parts are very compactly arranged, and. may be conveniently andeasily assembled or disassembled as desired. Because of the nature ofthe material from which the device is constructed, it may bemanufactured at a very low cost. The.

nozzle frame is made up of standard parts, the pipes being perforated,and no particu lar skill is necessary in the assembling of the device. i

The present embodiment of the invention has been disclosed in detail,since in actual practice, it attains the features of advantageenumerated as desirable in the statement of the invention and the abovedescription. It will be apparent, however, that numerous changes in thedetails of construction, and in the combination and arrangement of partsmay be resorted to if desired, without departing from the spirit orscope of the in-- vention as hereinafter claimed, or sacrificing any ofits advantages.

Having thus described my what I claim as new is An attachment of theclass described including a pipe adapted to be rested on the upper edgeof a wash tub said pipe having one end thereof engageable with a sourceof air, a second pipe threadedly engaged with the other end of the firstpipe and depending downwardly therefrom interiorly of the tub, a Tcoupling threadedly engaged with the lower end of the second pipe, a

invention.

pair of perforated pipes threadedly engaged with the T coupling toextend at right angles from the second pipe and in alinement with eachother, elbow couplings on the ends of the pair of perforated pipes, asecond pair of perforated pipes threadedly engaged with the elbows, asecond pair of elbows threadedly engaged with the second pair ofperforated pipes, and a perforated pipe engaged with the second pair ofel- 10 sole supporting means for the frame in the 15 tub.

In testimony whereof I affix my signature.
